Why Does the Paint on the Shell of an Ice Bath Chiller Machine Bubble and Peel?

Many people have experienced issues where the paint on the outer shell of an ice bath chiller machine starts to bubble and peel after some time. This can be caused by a variety of factors, including improper surface treatment before painting, mechanical damage during transportation or installation, and environmental conditions.

Inadequate Pretreatment Before Painting

Surface pretreatment is an important step before painting the ice bath chiller machine. The pretreatment before painting includes three steps: degreasing, rust removal, and phosphating.

• Degreasing is to remove pollutants such as grease, dirt, and dust from the metal surface. This step can prevent pollutants from remaining on the surface, hindering direct contact between the coating and the metal, resulting in poor adhesion of the paint, bubbling, and falling off of the paint.
• Rust removal refers to the removal of rust and old coatings through mechanical or chemical reactions to prevent rust from spreading under the paint and affecting the overall painting effect.
• Phosphating refers to the formation of a phosphating film on the metal surface through chemical reactions. This phosphating film can improve the corrosion resistance of the metal and also provide a good adhesion base for subsequent painting.

If the pretreatment before painting is not in place, and the steps of degreasing, rust removal, phosphating, etc. are not carried out, the adhesion of the paint will deteriorate, the anti-corrosion performance of the coating will decrease, and the life of the coating will be shortened.

Mechanical Damage During Transportation or Installation

Physical damage is another common cause of paint failure. During handling, especially at the edges or corners, the unit may be bumped or scratched. These seemingly minor impacts can chip or crack the coating, making it vulnerable to moisture and corrosion. Without proper packaging and careful installation procedures, even high-quality coatings can be compromised.

High Humidity or Long-Term Exposure to the Sun

If the ice bath chiller machine is placed in an area with high humidity, moisture will penetrate into the coating, causing the coating to have poor adhesion and blistering.

Once the coating of the ice bath chiller has begun to fall off, the metal is exposed to a high humidity environment and it is easy to oxidize and rust. And the rust will soon spread under the coating that has not fallen off.
When the ice bath chiller is placed outdoors for a long time under the action of high temperature and ultraviolet rays, the coating is easy to dry, fade, become brittle, crack, and eventually fall off.

What Should I Do if a Cold Plunge Chiller Has a Paint Problem?

If you find that your ice bath chiller machine has a paint problem, you should take action as soon as possible to avoid a bigger problem. You can follow the steps below to deal with it.

Remove the Problematic Coating

Use sandpaper to polish the peeling and bubbling parts. If the place where the paint peeled off has rusted, the rusted part needs to be finely polished. Clean the surface with degreaser, water, etc. to ensure that the surface is dry and free of residue.

Choose the Right Touch-Up Paint Material

The primer should be made of a material with anti-rust function, and the topcoat should be a UV-resistant and high-temperature resistant spray paint. If it is used outdoors, it is recommended to choose a color paint suitable for outdoor use. It is worth noting that you need to choose a spray paint color close to your cold plunge chiller unit.

Touch-up Paint

When painting, pay attention to the need to apply evenly and pay attention to the transition part with the edge. When spraying, you need to spray layer by layer. Multiple thin coatings can achieve better coverage.
At the same time, pay attention to drying. If you do the next layer before the previous layer of paint is dry, it may affect the effect of the spraying. It is not recommended to spray in a humid environment. A dry and ventilated environment is best.

Protective Measures

After the repainting is completed, corresponding protective measures can be taken according to the use environment. You can choose to apply transparent varnish, cover with protective film, protective cover and other methods to enhance the corrosion resistance of the shell spray paint and extend the service life.

How Does COLDCHILLER Ensure the Quality of Its Ice Bath Chiller Shell?

As a professional cold plunge manufacturer, COLDCHILLER has been dedicated to ice bath chiller machine for many years, consistently providing customers with high-quality cold therapy solutions.

To ensure long-lasting durability, the outer shell of every COLDCHILLER ice bath chiller undergoes strict pretreatment before painting. Each step—degreasing, rust removal, and phosphating—is meticulously performed to guarantee excellent paint adhesion and corrosion resistance. The paint we use is specially formulated for outdoor use. It is UV-resistant, heat-resistant, and applied in a dust-free workshop for maximum quality.

We use a two-layer coating system consisting of a primer and a topcoat. First, the primer is applied to the metal frame and then baked at high temperature to ensure strong bonding. After the primer, a layer of color paint is sprayed and also baked at high temperature to enhance durability and finish.

Every cold plunge water chiller undergoes a rigorous factory inspection process, with each step executed in accordance with strict quality standards. To prevent damage during transportation, we use protective foam packaging, ensuring that the unit arrives in perfect condition.

We also have a professional after-sales team to provide you with high-quality after-sales service. In addition, the chillers produced by COLDCHILLER have a one-year warranty period, giving you peace of mind and reliable service even after purchase. So you don’t need to worry about after-sales problems.

The cold plunge chillers produced by COLDCHILLER are sold all over the world and are loved by many people. If you need a chiller with certification, contact us now to get a quote. You may also be interested in the following:
